To all whomc't mag/onccm: c 4

Be it known that I, ALBERT jLorTsGAAR- DEN, citizen of the UnitedStates, residing at Powell, in the county of lPark yandfState ofWyoming, have invented certain new and useful AImprovements inDoorfClosers, of which the following is a specication:

My present invention hasj relation` to spring-actuated means for closinghinged oors.

The object of the invention is `to provide a simple, inexpensive andeasily installed d evice, designed more` particularlyfor use 'incombination with a screen door, at theouter side thereof, andconstructedl and arranged in ysuch manner that the spring is 4put undertension by the opening of thedoor, and serves when the door isthe door.yY a Other objects andadVantages of the invention will'be fullyunderstoodv from the following description and claims when the planethrough the spring and between the arms of the device and the door.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

The door 1 may be and l preferably is of conventional construction,

5 also be observed that the arm 7 is provided closed, to exert a ,oleverage against and thereby promptlyclose K is suitably secured on andfis 1 hinged in` the ordinary ywell known man-ner to the cas-` withaninner` end portion 10 which extends beyond the pivot point 8 and isconstructed with aiview to bringing up against the outer edge of the arm6,-therebyfobviating the possibility of the arms 46 and'7 being alinedand the spring located4 in improper position on the door.

.In the present 'and' preferred embodiment of my inventionand for `thevsake of attaining lightness, of the arms .6 and 7 is formed of a singlepiece of sheet-metal bent upon itself with the bight 11 of the bendoutermost or remote from the door as shown. The outer end portions ofthe arms are bifurcated tov straddle the flanges 5 of their respectivebrackets 3, 4', and the inner end portion of .the arm 6 is bifurcatedforthe reception and play of the extended end portion 10 of the arm 7.

One end of the spring 9 is connected `in any approved manner to theouter side of the door 1, and the other end of the sprinv' a nut 12. Thesai nut 12 receives a threaded bolt 13 which takes through one in thebight of the arm 7 and has its head 15 opposed to the outer side ofthesaid bight. The nut 12 and bolt 13, arranged as stated', constitute ahighly efficient regulating means for the spring as will be readily oappreciated when it is stated that mere turning of the bolt 13 will beattended by tightening or loosening of the spring according to thedirection in which the bolt is turned. The plurality of holes 14 isprovided in order that the spring may be'positioned as variousconditions require relatively to the arm7.

In the practical-use of my novel device, it will be manifest thatopeningvof thedoor 1 will be attended'by flexing of the connected arms Gand 7 and expansion of the spring .9, and that consequently when theopened door is released the spring by contracting to its normal statewill operate to promptly return the arms 6 and 7 to their normalpositions and by so doing will securelyclose the door; f

also, that normally the spring-controlled device will serve toyieldingly hold the door in closed position as is desirable.

The arrangement of my improvement at the outerside o f the door andadjacent to the hinged edge thereof, is materially advantageous inasmuchas it precludes the poscheapness and strength, eachy of a series ofapertures 14 sibility of the improvement interfering with the usualmanipulation of the door.

Having described my invention, what I claim and desire to secure byLetters Patent, is:

l. A springeactuated door-closing device, comprising brackets adaptedfor connection to a door casing and a door, respectively; said bracketshaving outwardly extending flanges, an arm formed of a strip ofsheet-metal bent upon itself and having a bifurcated outer end portionreceiving and pivoted to the door-casing bracket, an arm formed of astrip of sheet-metal bent upon itself and having a bifurcated outer endportion receiving and pivoted to the iange of the door bracket; the saidarms being pivoted together adjacent to their inner ends, and one armhaving an inner extended end portion movable in a bifurcation of theother and adapted to bring up against the back edge of such other, aretractile spring adapted at one end for connection to a door, and aconnection between the other end of said spring and the armcomplementary to the door-bracket; said connection being ar- Gopies ofthis patent may be obtained for ranged in an aperture in the bight ofthe arm.

2. A spring-actuated door-closing device, comprising brackets adaptedfor connection to a door casing and a door, respectively, an arm formedof a strip of sheet-metal bent upon itself and pivoted at its outer endto one bracket, an arm formed of a strip of sheet-metal bent upon itselfand pivoted to the other bracket; the said arms being pivoted togetheradjacent to their inner ends, and one arm having an inner extended endportion movable in a bifurcation of the other and adapted to bring upagainst the back edge of such other, a retractile spring adapted at oneend for connection to a door, and a connection between the other end ofthe spring and one arm; said connection being arranged in an aperture inthe bight of the arm.

In testimony whereof l affix my signature in presence of two witnesses.
